Apply roof sealant along the top edge and sides of the vent and use sealant to cover any exposed roof nails

Image

A bathroom exhaust fan can be installed to vent either out through the wall or up through the roof.

Image

Match the pipe sleeve inner diameters with the outer diameter of the plumbing pipes to be insulated

Image

These copper plumbing pipes should be insulated.

Image

The pulleys in this old window frame were once used for counterbalancing weights to help raise and lower the window; this window can be restored with new pulley ropes or the weight pockets can be insulated with caulk and rigid insulation.

Image

Latches were added to this attic access panel to hold it more tightly against the weatherstripping for better air sealing when closed.

Image

Old window weights can be removed and the cavities on each side of the window can be filled in with rigid foam, then new jamb liners and spring balance hardware can be installed.

Image

Weatherstripping has been installed along the framing of this attic access panel to air seal the opening.

Weatherstripping has been installed along the edge of this attic access panel to air seal the opening.

Image

This attic access hatch has no insulation dam, allowing insulation to escape through the gap when the hatch is opened

Image

An insulation dam should surround the attic access and allow blown insulation to be installed to the required depth.

Image

An insulation dam was constructed out of 2x8s that sit on ceiling joists for this attic access hatch.
